Abstract

The invention belongs to the field of ultra-precision machining equipment and relates to a longitudinal rack polishing machine. The longitudinal rack polishing machine comprises an automatic discharging mechanism, a PLC (programmable logic controller) electrical control box, an automatic feeding mechanism, a frame, a touch screen control board, an automatic shape modifying mechanism, a polishing mechanism and a centre driving mechanism. A nylon resin polishing wheel is adopted for longitudinal polishing of a tooth back portion and a shaft portion of a rack. The polishing wheel in high-speed rotation has a certain floating quantity and can completely fit the rack, and the polishing wheel has a certain precompression force on the rack by the aid of a servo motor and a pressure sensor. Angular rotation of the rack is also realized under action of the servo motor, and full coverage of the tooth back portion can be realized. The servo motor drives the polishing wheel to move longitudinally to meet requirements of workpieces in different lengths. In electrical control, A PLC and a touch screen are adopted for controlling, and the servo motor and an air cylinder serve as power sources to be responsible for all operation instructions of equipment and implementation.

Description

technical field

[0001] The invention relates to a longitudinal polishing machine for racks, which effectively solves the problem of longitudinal polishing of racks. It belongs to the field of ultra-precision processing equipment. Background technique

[0002] At present, all rack polishers produced in China use abrasive belts or whetstones to form axial polishing lines on the surface of the rack, which cannot meet the requirements of electric steering gears. Based on this, we have developed a longitudinal polishing machine for racks, so that the polished racks can form longitudinal polishing lines on the basis of meeting the requirements of surface finish to meet the requirements of electric steering gears. It fills up this gap in the country. Contents of the invention

[0003] The invention provides a rack longitudinal polishing machine. The equipment uses a nylon resin polishing wheel to longitudinally polish the toothed back and shaft of the rack. While the polishin...

Examples

Embodiment Construction

[0018] refer to figure 1 , figure 2 , image 3 As shown, the rack longitudinal polishing machine of the present invention is driven by an automatic feeding mechanism 1, a PLC electrical control box 2, an automatic unloading mechanism 3, a frame 4, a touch screen control panel 5, an automatic shaping mechanism 6, a polishing mechanism 7 and a top drive The organization consists of 8. The automatic feeding mechanism 1 is connected to the frame 4 through a bolt group; the PLC electrical control box 2 is connected to the touch screen control panel 5 through a data bus; the automatic shaping mechanism 6 is connected to the polishing mechanism 7 through bolts; the automatic unloading mechanism 3 is connected to the frame 4 is connected by a bolt group; the top drive mechanism 8 is connected with the frame 4 by a bolt group; the top drive mechanism 8 is respectively connected with the touch screen control panel 5 and the PLC electrical control box 2 by data lines.
